Subject: scsi: qla2xxx: Fix session hang in gnl
From: Quinn Tran <qutran@xxxxxxxxxxx>
commit 39d22740712c7563a2e18c08f033deeacdaf66e7 upstream.
Connection does not resume after a host reset / chip reset. The cause of
the blockage is due to the FCF_ASYNC_ACTIVE left on. The gnl command was
interrupted by the chip reset. On exiting the command, this flag should be
turn off to allow relogin to reoccur. Clear this flag to prevent blockage.
